Can Christians be more rigorous about where they give, and how much difference each dollar actually makes? JD explores this with Tim Barker, founder of ROI Ministry, which researches Christian charities to identify giving opportunities that produce high levels of measurable "kingdom impact per dollar." Tim shares how losing his business led him to rethink Christian stewardship, why so little Christian giving reaches the world's poorest and least-reached people, and how ROI Ministry evaluates organisations working in evangelism, discipleship, clean water, healthcare, housing and human trafficking prevention. They also discuss the difference between outputs, outcomes and genuine impact, the difficulty of measuring spiritual change, and how much confidence donors should place in metrics like decisions for Christ or children discipled.

Can the existence of this extraordinary world really be explained without God, and what does that mean for how we give? JD explores this with Philip Swenson, philosopher at William & Mary, whose work on moral epistemology and the problem of evil brings rigorous academic philosophy to bear on the most practical questions facing Christians who want to change the world. Phil unpacks his extraordinary world argument for God's existence, and why the infinite value of human connection in heaven might be the most compelling reason yet to give generously to the global poor.

Can mobile money really save whole percentage points of a nation's GDP, and unlock an economy in the process? JD explores this with Ben Kolesar, Operations Lead at Wave Mobile Money, whose unlikely path from Congressional staffer to fintech pioneer brought him to the front lines of financial inclusion across Sub-Saharan Africa. Ben unpacks the painstaking work of launching mobile payments from scratch in a new country, the fish traders who became Wave's unlikely first customers in Senegal, and why the most powerful thing a tech company can offer the world's poorest people is simply a cheaper, more reliable way to move money.
